Dear student
There will be two components of tension
T cos theta = mg
T sin theta = qE
Hence
Tan theta = qE/mg
E = mg tan thata/q
Sigma/epsilon = mg tan theta/q
Hence
sigma( surface charge density) = mg * epsilon* tan theta/q

T cos theta = mg
T sin theta = qE
Hence
Tan theta = qE/mg
E = mg tan thata/qbbk.
hope it is right answer.
